To all whomt mayconcera:

Be it known that LEDWARD I-I. MnnsMAN, a citizen. of the United States,residingat Celina, in the countyof Mercer and State of Ohio, haveinvented certain new and useful Improvements in Extension-Tables," *of*which the following `is a specification.

Y My invention relates to improvements ink extension tables, and moreparticularly to' extension tables whereiny the extension is effectedthroughv the agency of a leaf per-l` manently associatedwith the tablestruc= i ture, and arranged to be hidden from view,

when the tableis closed.` l j .l One of the particular objects of myinvention is to provide a construction ywhere-y by round tables,andtables having a rim set: in somewhat from theedge of the table top,maybe equipped with such a folding leaf.l

In the drawing,` wherein I have illustrated Van embodiment of myinvention, 2F ig` lure 1 is a bottom plan view, withl parts Ain section,showing a round, rimmed, table equipped with `myfinvention, inclosedposition; Fig. 2 is a cross section on line `2-42 of Fig. 1; Fig.3is across section on line of Fig.x 1; Fig. 1; is a view,similar to`Fig;vr 1, showingthe `table in opened po-y sition; and Fig.y 5 isa`section on Vline 5-5 'In the drawingsi1l)y and 10a indicate table- Y 12indicates ya pedestalof any suitable conl struction, herein. shown as anon-.dividing pedestal, supporting the usual bridge cap 13. cured, as at15, to the bridge inusual fashion and coperate'with the inner slide pair16 and the outer slide pair 162L in usual fashion.l The slides 16andy16aare secured to their respective tabletop sections 10 and 10a in suchfashion as to leave a clearance space of suitable depth between the.central portion ofthe tablejtop `sections andthe tops of the slidesfor'the reception of the concealable leaf to be described. Tothis end,blocks 17 and 17 a are interposed ,between theslide members 16 and 16aand the respective tabletop sections, 10 and 10a, the slides beingsecured to the table-top sections, through said interposed blocks, onlyat their outer extremities, as indicated at 18, such fasten` ings beingshown throughout as screws for purposes of clear i The middle pair ofslides 111 are se-y y speciacaftiori of Lettersratent. 1rv1;"15611159'Jd Spt, 1, 1914 Appiiationmedaugutnisii. seriainaeziacae.`f

llu'stratioii.. The ybridge cap 13K also has secu'redthereto, kas at 19,just inside of the slide, apair of lfraine strips IQOKwhich at one endare -spannedby a cross so l .

To its longitudinalside -edges (parallel with the slides) arepivot-l' connection ,between theedge plates or sec-` tions'fand the bodyof the leaf are preferablyk made through spring hinges 27,' of wel]known constructiomwhich tend to holdthe f fplatesin horizontalalinenient with the leaf-bodyy'llhejco-acting edges "of the edge vplatesand'body ymay 'be correspondingly tongued and .l grooyed to increase:the strengthk ofthe joint and insure 'fitting of the parts.y r The edgemembers -26 carryrim sections k11"'ian'd` provision conveniently rnayybe made for latching each edge memberk depressed or ,retractedl positionbyy mountr` f f `ing on the under side ofthe .body 25g a f;

the rim section 11-,r as 2shown in Fig. 2.'

Upon the under side ofthe leaf body 25,

just inside Lof they frame` members 20, I se# cure, as at31.',mstrips-32, andy connectthel strips SZKtotheframe membersQO byparal-J, I'lel swinging links'SS, each arranged in a triangularrecess31` yin the frame strip 20.?

Forfraising and loweringthe leaf'on these swinging linlr inernbers, Iprovide a suite-v able] oscillating handleupon the cross beam 21 of theframe members 20, and con-f` nect it by a distance-rodf?, with the leaf,,the operating.,oscillatory` `3,6 being preferf j y ably of ywell iknownconstruction, arranged` to throw the` end of theV rodBl attached'`thereto past deadl center forftoggle.A locking action when the handle isoperated to 'ele` vate the leaf. Suitablefdowels l38 are pro'- vided`for effecting connection betweenthe f edges of thefleaf body and theyedge memi bers,-and the adjoining tableltop sections;

Iny operation, when 'it-is desired to extend ,the table, the table-topsections are :pulled-v apart, their slide members 16 and 16aslid5ing'inL the slide member 141 `-attachedto the j pedestal, and leavingbetween the table-top sections a space somewhat wider ,than the iosfleaf 25. The edge'members of the leaf are ,1

ward and upward, raising it to the level of the tablestop sections, andthen, when the table-top sections are pushed together, the

dowels effect rigid connection between all parts of the enlarged top.

For reduction of the size of the table, the

operation is reversed, the table-top sections being pushed' opensufficiently to give the necessary clearance, the operating handle 36reversely moved to drop the leaf into its lowest position whereit standsin the space between the plane 0f the slide 14 and the 'plane of thetable top sectionJ ythe edge members 26 of the leaf being then forced todepressed position and there latched, and the table-top sections thenbeing moved to closed position to overlie and completely conceal theleaf. It will be observed thatwhen the table is closed, the leaf withits edges infolded is completely containedv within the smaller circle ofthe rim 11, but that when open and raised it fills out the full widthof. the table, and provides a continuation :of the rim.

While I have herein described in some ldetail a particular embodimentofmy invention, it will be apparent to those skilled in the art thatchanges in the details thereof might be made without departurefrom thespirit 0f my invention `and within the scope of the appended claims.`y'f 4 What I claim is:

1. In an extensionl table, the combination. of a set of three slidepairs; a bridge con-` nectin'g the central pairof slides; top sectionsIcarried by the inner and outer slide pairs', adapted to meet when thetable'is closed, and mounted above their slides to leavea'centralclearance space between the slides and top sections; a lea-fadapted toit intovsaid clearance space, comprising a'body part, and infolding side'edge portions ,j a frame carried by said bridge and at one Vendextended therebeyond under oneof the table top sections; swinging linkscarrying the leaf-body, pivoted to said frame; an actuating levercarried by said extended end of the frame; anda connection between saidlever and the leaf-body to elevate the leaf on its links when the leveris moved to one position.

2. In an extension table, the combination of slidable semi-circular topsections, slide vide lbetween the slides'and top sections a clearancespace, a pedestal supporting the i slides, a leaf body of size to`permit inclusionl thereof in said clearance space within the confinesof the top when the latter is closed, parallel links'connected to thesaid leaf portion and to a pedestal-carried part, said part extendingbetween the slides toward the edge `of one of the table top sections,means upon said extended end of the said part to move 'said leaf portionupon said links into or out .of the plane of-the table-top, and edgesections pivoted. to the edges of said leaf portion.

y 3Q In an extension table, the combination of a set'of three slidepairs; a bridge'connectingv the slides of the central pair; top

sections carried by the inner and outer slide fpairs, adapted to meetlwhen the table is clsed` and mounted above their slides to Lleave acentral clearance space between the @slides and the top sections; a leafadapted to lfit into said clearance space comprising a body portion andhinged edge portions;v -a frame having sides secured to the bridgebetween the slides and at one end extending therebeyond under one of thetable top sections; guide strips secured to the leaf body lbetween thesides of the frame; swinging links connecting the said frame sides andguide strips and mea-ns on the frame extension formovmg the leaf on itsswinging` link connections. v

i 4. In an extension table, `the combination 4of 'a set of three slidepairs, a bridge coni gnecting the slides of the central pair, topsections carried by the `inner 'and outer slide pairs adapted to ymeetlwhen thetable is 4,closed and anounted above the slides to leave acentral clearance space between the slides and the top sections`,'a leaf'adapted to fit into said clearance space comprising a body portion andhinged edge portions, a frame comprising two sidemembers each secured4upon Athe bridge parallel to the slides and extending beyond one edgeof the bridge, and a cross member connecting said ex*- tended ends ofthe said members, guide .strips secured to the leaf body parallel tosaid members of the frame, swinging links connecting said side membersof the frame and the respective guide strips of the leaf body, anactuating lever carried by said cross member of the bridge-carriedframe, and a `connection between said lever and leaf body to move a leafon'its link by'means of saidV l lever.

In testimony whereof I hereunto 'set myl hand in the presence of twowitnesses. members secured to the top sections to proi 2 EDI/VARI)HJMERSMAN. In the presence of- MARY F. ALLEN, W. LINN ALLEN..
